HEADLIGHT.

Application filed August 16, 1921.

in Headlights, of which the following is specification.

This invention relates to headlights particularly adapted for use on motor vehicles to illuminate the road in advance of the mov ing vehicle.

'lhe main object of the invention the production of a headlight which will project all of the illuminating rays from the lamp directly forward and downward and permit no rays to be projected upwardly into the eyes of approaching pedestrians or onto the Windshields of vehicles moving in either direction iii-front oi the headlight.

A further object oi the invention is the provision 01' means whereby some of the illuminating rays from the lamp will be defiected rearwardly from an opaque vizor in front of the. lamp onto the reflecting surface within the casing from which said rays, greatly intensified will be projected.

A rurther object of the invention is the provision of an opaque vizor having a plurality of curved reflecting surfaces formed in its inner face, these surfaces being adapted to deflect a portion of the lamp rays into the interior of the casing.

The invention consists primarily in tending the reflecting surface in the casing downwardly over the upper wall of the cas ing and terminating it at a point adjacent the bottom of the lamp thereby making it impossible to project any of the illuminating rays upwardly. V

The invention consists further in a vizor of peculiar construction provided on its inner face with a plurality mirrored surfaces adapted to deflect a portion of the lam rays rearwardly into the casing.

' 'lfie invention further consists in certain novel features of construction and arrange ment of parts which will be understood readily by reference to the description of the drawings and to the claims to he hereinafter given.

For the purpose of illustrating the invention, one preferred form thereof is illustrated in the drawings, this form having been found to give satisfactory and reliable re sults although it is to he understood that the Serial No. 492,806.

various instrumentalitics of which the invention consists can be variously arranged and organized and the invention is not limited to the precise arrangement and organization of these instrumentalities herein shown and described except as required by the scope of the appended claims.

()f the drawings:

Figure 1 represents a side elevation of a headlight embodying the principles oi the present invention.

Figure 2 represents a front elevation oi? the same.

Figure 3 represeuts'a vertical section of same on line 3, 3, on Fig. 2. t

Figure i represents afront elevation of same with hood and retaining liIll removed, and

Figure 5 represents a plan of the hood drawn to a reduced scale.

Similar characters indicate like parts throughout the several l urcs of the drawings.

In the drawings, i0 is the usual headlight support adapted to be secured to a motor vchicle and having attached to its upper end the casing 11.

, \Vithin the casing 11 is a reflector 12 which extends over the upper portion of the inner wall of the casing 11 and terminates at 13 slightly below the center of said casing, thereby leaving the lower part of the blackened inner wall of the casin exposed to view. 3

Axially disposed in the casing 11 and supported in the reflector 12 near its lower horizontal edge 13 is the lamp 14 to which electric current is supplied through the wires 15 e gte nding outwardly through a tubular mono-her "l0 mounted in the casing 11.

in order to get best results from the lamp 14, the filament 17 thereof is disposed. vertically therein.

The front end of the casing 11 has mounted therein, the clear lens 18 which is secured in pos'ion by means of the retaining ring 19 which may be looked to the casing 11 in any well-known manner. I

in 'tront of the lens 19 is a vizor 20, the rear end of Which has a iiange 21 inserted between said lens 18 and the lront part of the retaining ring 19.

The visor is-provided with a plurality ofcurved depressions formed by the inwardly extending ridges 22, 23 and. the front Wall. 241- This front well has a. portion thereofivert n 3. 3 f T1109 the i U illuminating rays from the lamp M- p 5 ed onto said mirrored sur tical and the entire inner surface of the ViZOIK end termina 2G is mirrored so that a great parface are ieiiec fchereo h each previried with a IIUWOI 1" dBPK'GSSlOl'IS being W or sent CHSHIE.
